docs(portfolio): add created-tokens and dev wallet capabilities to description

Previous description omitted portfolio created-tokens (dev wallet token
history, ATH market cap, graduation status) and token-balance sub-commands.
Added "tokens created by a developer wallet (with ATH market cap and DEX
graduation status)" and corresponding trigger phrases so agents match
queries like "what tokens has this dev launched" or "highest ATH token
this dev ever created".
